髌股关节痛(PFP)是一种常见的肌肉骨骼疼痛，尤其是女性。髋部肌肉力量减弱已被认为是一个促成因素，但疼痛、髋部肌肉力量和功能之间的关系尚不清楚。这项研究的目的是检验疼痛和髋部肌肉力量可以解释PFP女性功能状态差异的独特部分这一假设。一项观察性的队列研究。女性PFP患者21例，年龄26±7岁，身高163±4 cm，体质量62±10 kg。受试者的最短疼痛持续时间为2个月，平均疼痛持续时间为4.9±3.6年。用视觉模拟评分(VAS)测量单侧下蹲时的疼痛；臀中肌、臀大肌和髋关节外侧旋转肌的等长肌力；吉贾拉评分(自我报告功能测量)。以Kujala评分为因变量进行分层多元回归分析。疼痛和髋关节外侧旋转肌力量是自变量，按顺序输入。其他力量指标与吉隆坡的得分没有相关性，因此，分析中没有使用其他力量指标。疼痛可以解释吉贾拉得分差异的22%(p=0.03)。在考虑疼痛程度后，髋关节外侧旋转肌的力量可以解释另外14%的差异(p=0.06)。疼痛和髋关节外侧旋转肌力量与女性PFP的功能状态有关。改善疼痛和髋关节外侧旋转肌力量可能会改善患有这种常见疼痛状况的女性的功能。
Patellofemoral pain (PFP) is a common musculoskeletal pain condition, especially in females. Decreased hip muscle strength has been implicated as a contributing factor, yet the relationships between pain, hip muscle strength, and function are not known. The purpose of this study was to test the hypothesis that pain and hip muscle strength explain unique portions of variance in the functional status of females with PFP. An observational, cohort study. Twenty-one females with PFP (age: 26±7 yrs; height: 163±4 cm, and body mass: 62±10 kg,). Subjects had a minimum pain duration of two months (mean pain duration: 4.9±3.6 years). Pain during a unilateral squat measured with a visual analog scale (VAS); isometric muscle force of gluteus medius, gluteus maximus, and hip lateral rotators; Kujala score (self-report measure of function). Hierarchical multiple regression analysis was performed with Kujala score as the dependent variable. Pain and hip lateral rotator muscle strength were independent variables, entered in that order. Other strength measures were not correlated with the Kujala score, and as such, were not used in the analysis. Pain explained 22% of the variance in the Kujala score (p=.03). Hip lateral rotator strength explained an additional 14% of the variance, after accounting for pain level (p=.06). Pain and hip lateral rotator strength contributed to the functional status of females with PFP. Improving pain and hip lateral rotator muscle strength may improve function in females with this common pain condition.
